In the cryptocurrency space, survival is always the top priority. Don't wait until opportunities are everywhere and then be forced to exit early with nothing. Based on years of experience, I have compiled seven practical survival rules that I still follow today, and I want to share them with everyone.

Rule 1: Bitcoin as the key guide for the market. Bitcoin's price movements often set the overall market tone. Occasionally, Ethereum may temporarily decouple, but the vast majority of altcoins cannot escape Bitcoin's dominant influence.

Rule 2: Bitcoin and Tether (USDT) often have an inverse relationship. When Tether's price rises, Bitcoin tends to decline; conversely, during strong Bitcoin rallies, it is usually wise to switch to Tether.

Rule 3: Midnight to early morning hours are prone to sharp price fluctuations. Setting buy orders at low prices and sell orders at premiums before sleep can sometimes lead to automatic trades and unexpected gains.

Rule 4: The 6 to 8 AM window often indicates the day's direction. If prices continue to fall from midnight to 6 AM and remain downward in the morning, a rebound is likely later in the day; conversely, if prices rise in the first half of the night and continue upward in the morning, a correction may occur that day.

Rule 5: Be cautious of market volatility around 5 PM. Due to international time differences and overlapping trading hours in Europe and America, sharp rises and falls are more likely, requiring vigilance.

Rule 6: Black Friday events deserve extra attention. Historical data shows occasional sudden crashes on Fridays, but this is not an absolute rule—use it as an auxiliary signal.

Rule 7: Coins with good liquidity are more resistant to declines. As long as the project is not a scam coin, downturns should not cause excessive panic. If you have idle funds, consider adding gradually; if not, be patient and wait for recovery.

These rules aim to improve decision-making. In practice, adjust them according to your personal situation. Remember, risk control is key to long-term participation.
